Infant Spitting Up

Spitting up is extremely common in healthy infants, with about half of all babies experiencing some degree of reflux in their first three months. This happens because the muscle between the esophagus and stomach (lower esophageal sphincter) is still developing and may allow stomach contents to flow back up. While most spitting up is harmless and resolves on its own by 12-18 months, some babies develop gastroesophageal reflux disease (GERD) requiring medical attention. Understanding the difference between normal spitting up and problematic reflux helps parents know when to seek help and ensures babies receive appropriate care for optimal growth and comfort.

⚠️ Seek Medical Attention For:

  • Forceful or projectile vomiting
  • Poor weight gain or weight loss

  • Chronic coughing or wheezing
  • Difficulty breathing
  • Excessive irritability or crying

Normal Spitting Up vs GERD

  • No signs of pain
  • Decreases with age

GERD Signs

  • Feeding difficulties
  • Irritability during/after feeds
  • Arching back
  • Respiratory problems

Peak Age

  • Begins: 2-3 weeks
  • Peaks: 4-5 months
  • Improves: 6-7 months
  • Resolves: 12-18 months
  • Sitting up helps
  • Solid foods help
